augmentative and alternative communication (AAC)
Are there any risks or side effects of AAC?
AAC has no medical side effects and does not stop a child from speaking — research shows it usually supports and often increases spoken language. The real considerations are practical: choosing the right system, family training, and avoiding abandonment, all managed by a qualified speech therapist.

When a child uses pictures, signs or a speaking device to be understood, parents often ask: could this hold back their talking? The reassuring evidence says no.
In short
Augmentative and alternative communication (AAC) — picture boards, sign, or speech-generating devices — is safe and carries no medical side effects. The biggest worry parents have is the myth that AAC stops a child from speaking; decades of research show the opposite: AAC tends to support and often increases spoken words, because it lowers frustration and gives a child a reliable way to connect. The real risks are practical, not harmful — choosing the wrong system, abandoning it too soon, or not training the family — and a skilled speech therapist prevents these.The honest picture of "risks"
AAC is not a medicine, so there are no physical side effects. What to be aware of instead:- The "it will stop speech" myth — this is the commonest fear and it is not supported by evidence. AAC gives a child a voice now and frequently encourages more vocal attempts, not fewer.
- Wrong fit — a system too complex (or too simple) for a child's current abilities can cause frustration. The right match comes from proper assessment, not guesswork.
- Abandonment — devices or books get set aside if the family and school aren't shown how to use them daily. Consistent modelling by adults is what makes AAC succeed.
- Over-reliance on prompting — if a child is always physically guided, they may wait to be prompted. Good therapy fades support so communication becomes the child's own.
- Frustration during the learning curve — early days can be slow; this settles with patience and coaching, and is far gentler than the frustration of not being understood at all.
None of these are reasons to delay AAC. They are reasons to begin it with a qualified team who reviews and adjusts the system as your child grows.
When to seek guidance
If your child struggles to be understood, gets frustrated when communicating, or speech is significantly delayed, a speech-language assessment helps decide whether AAC could help and which type suits your child best. AAC is introduced and reviewed by a speech therapist — never bought blindly online — so it stays the right fit over time.The Pinnacle way

What to watch
Watch for frustration when your child tries to communicate, speech that stays significantly behind peers, or an AAC system being set aside at home or school — signs it may need reviewing for fit.
Try this at home
Model the AAC system yourself — point to pictures or use the device while you talk during everyday play and meals. When adults use it too, children learn it's a natural, valued way to connect.

Frequently asked
Will AAC stop my child from learning to talk?
No. This is the most common worry, and research consistently shows the opposite — AAC tends to support spoken language and often increases vocal attempts, because it reduces frustration and gives your child a reliable way to connect.
Are there any physical side effects of AAC?
AAC is not a medicine, so it has no physical or medical side effects. It is simply a way of communicating using pictures, signs or a device. The only considerations are practical, such as matching the right system to your child.
Can I just buy an AAC app or device myself?
It's best not to choose blindly. A speech therapist assesses your child's current abilities and matches the right system, then reviews it as your child grows — this prevents the common problem of a device being set aside because it didn't fit.
